Thank you for viewing. I am selling a trombone mouthpiece. - Vincent Bach 5G - For large shank, silver-plated - No box This is a mouthpiece for a trombone. - Cup inner diameter: 25.50mm - Cup depth: Deep It has been used, but there are no major scratches or dents, and I think the condition is relatively good. The Bach 5G is a standard model mouthpiece. Personally, I think it's a mouthpiece that can produce a very full and warm tone. Type...Trombone Accessories/Parts...Mouthpiece
